摘要
在含砷矿石的开采、选矿、冶炼过程中产生的废水和采用含砷浮选药剂处理矿石后产生的废水统称为矿冶含砷废水。随着我国对矿山环保政策的不断加强,矿冶含砷废水的净化处理成为绿色矿山建设的基本要求。本文概述了矿冶含砷废水的来源,详细阐述了矿冶含砷废水的净化处理技术,如化学沉淀法、电化学法、吸附法和生物法等,并进行了展望。
Wastewater,which are produced in the mining,beneficiation and smelting process of arsenic-bearing ores and produced after the ores treatment using arsenic-containing flotation agents,are collectively referred to as arsenic-containing wastewater.With the strengthening of environmental protection policy for mines in China,the purification of arsenic-containing wastewater from mining and metallurgy has become the basic requirement of green mine construction.In this paper,the sources of arsenic-containing wastewater of mining and smelting are summarized,and the purification and treatment technologies of arsenic-containing wastewater from mining and smelting are described in detail,such as chemical precipitation method,electrochemical method,adsorption method and biological method,etc.,and the prospect is speculated.
